Parameterized Cable Wall Passthrough - hide cables in your wall

What's this thing for?

This part is designed to be installed in a hole in your drywall and to allow cables to pass invisibly from behind a TV, into the the wall, and back out into the back of your entertainment center where your receiver, media players, gaming consoles, etc are kept.

Why is the hole blocked off?

This model uses built-in supports, both for the shroud and for the screw hole counterbores. These are to be removed after the print either by hand or with pliers. Because these are designed in, your slicer's support option should be disabled. 

Why'd I make this?

I designed this model because I got a new TV and wanted a clean way to route the cables from behind the TV to the back of my entertainment center without them being visible. There are commercial options available but some are really expensive and none of them allowed me to customize their appearance/design (and let's be honest, it's another excuse to print stuff).

What does "parameterized" mean?

If you're just printing the STL and don't care about customizing it, you can skip this part. For those still reading, Fusion 360, like many modern 3D CAD tools, allows you to create parameters, sort of like variables in programming, to store useful values related to your model. For example, I have a parameter for screw hole offset in both x and y that tells the model how far from each edge the 4 holes should be. By opening the model up in Fusion, you'll be able to see and edit these parameters. You might want a larger or smaller plate than I did. You can dial it in. You might have thicker/thinner drywall, or you might need a bigger opening. This is all stuff you can easily adjust with the free version of Fusion without having to know anything about how to use the software. Simply select Solid  from the ribbon at the top, choose Modify, then Change Parameters. There you'll see a list of what you can change, and as you change values you'll see the model adjust itself in response (you may have to drag the parameter window off to the side). Once you're done press Ok. Now select cable wall passthrough, the root of the model tree on the left side of the screen toward the top, right click it, and select Save as Mesh. Press Ok and you'll see a dialog where you can choose what to call it and where to save it. Press Save, and your STL is ready to print.

How should I print this?

I'll give you the settings I used, but this one isn't going to be very picky about material or other settings. Overall you're going to want to make sure your cooling settings are tuned for good quality overhangs. I won't get into the details but here's a nice guide if you need help.

The part should import into your slicer already in the correct orientation for printing.

Perimeters: 4
Top/Bottom Layers: 4
Infill: 40%
Supports: Off (because they're built in to the design)

Remember to remove the supports and the end from the passthrough hole and the counterbore portion of the screw holes.

What should I do if I run into problems with the model?

Feel free to leave a comment with suggestions for improvement, questions, or requests for help. I'd be glad to help you to the best of my ability. I'm not on Printables 24/7 but should usually respond in a day or two at the latest.
